Versuchsvorschrift

19.1 g (44.1 mmol) of the compound of Example 43A are provided in 367 ml of conc. acetic acid, 23.5 g (11.0 mmol) of palladium on activated carbon (5%) are added, and the mixture is stirred under a hydrogen atmosphere at room temperature overnight. The reaction mixture is subsequently filtered, the filtrate is concentrated, the residue is taken up in dichloromethane and washed with an aqueous sodium bicarbonate solution, and the organic phase is dried over sodium sulfate and concentrated. 12.7 g of the title compound with 63% purity (53% of theory) are obtained.
